Fixing CalculateWeeklypay Methods Of Employees?

I have now four types of employees. Managers (who receive a fixed weekly salary), Design workers (who receive a fixed hourly wage for up to the first 40 hours they work and "time-and-a-half," i.e., 1.5 times their hourly wage, for overtime hours worked), Sales workers (who receive a $250 plus 5.7% of their gross weekly sales), and Manufacturing (who receive a fixed amount of money per item for each of the items they produce -- each manufacture in this company works on only one type of item). and here are my classes:

employee class

the problem is i get this output:

You chose to open this file: Employees.txt
John Smith Manufacturing 6.75 120 444
0.0
Betty White Manager 1200.0 0 111
0.0
Stan Slimy Sales 10000.0 0 332
250.0
Betty Boop Design 12.5 50 244
0.0

meaning that it is getting 0 for all my calculations and leading to this weekly report:

WEEKLY PAY REPORT FOR Wacky Widgets COMPANY
Employee
0
WEEKLY PAY
250
Total Payroll: $0.0
Total number of managers paid:1
Total number of Design Employees paid:1
Total number of Sales Employees paid:1
Total number of Manufacturing Employees paid:1

fixing my methods so they can accept the integers of the file and use them in the calculation since all im getting at the moment are 0 values.

here is the abstract class from which all the other employees type are extending from

public abstract class Employee {
public abstract double calculateWeeklyPay();
private String fName;
private String lName;
private int EmpId;
private Position p ;
